I am going to be teach my student about the FOIL method of multiplication. In order to do that, I thought it would be a nice visual helper if I could draw arrows curving from one number to another and I was wondering if that was possible with LaTeX.
For example if I have
(a + b)*(c + d), I want to draw an arrow coming out of "a" going over "b" and terminating at "c". Can that be done with LaTeX?
Thanks for any input!
